FIELD OF INVENTIONThis invention generally relates to a system and method for completing a transaction, and more particularly, to completing a financial transaction using Radio Frequency Identification (RFID) in contact and contactless transactions.BACKGROUND OF THE INVENTIONLike barcode and voice data entry, RFID is a contactless information acquisition technology. RFID systems are wireless, and are usually extremely effective in hostile environments where conventional acquisition methods fail. RFID hasestablished itself in a wide range of markets, such as, for example, the high-speed reading of railway containers, tracking moving objects such as livestock or automobiles, and retail inventory applications. As such, RFID technology has become a primaryfocus in automated data collection, identification and analysis systems worldwide.Of late, companies are increasingly embodying RFID data acquisition technology in a fob or tag for use in completing financial transactions. A typical fob includes a transponder and is ordinarily a self-contained device which may be contairiedon any portable form factor. In some instances, a battery may be included with the fob to power the transponder. In which case the internal circuitry of the fob (including the transponder) may draw its operating power from the battery power source. Alternatively, the fob may exist independently of an internal power source. In this instance the internal circuitry of the fob (including the transponder) may gain its operating power directly from an RF interrogation signal. U.S. Pat. No. 5,053,774issued to Schuermann describes a typical transponder RF interrogation system which may be found in the prior art. The Schuermann patent describes in general the powering technology surrounding conventional transponder structures. U.S. Pat. No.4,739,328 discusses a method by which a conventional transponder lilay respond to a RF interrogation signal. Other typical modulation techniques which may be
